Then move down along your outboard gear matching each input and output to the same level. This puts your whole insert channel at unity. Then, check the DAW meter for the input returning from your gear and adjust the input level on the A/D converter so that the DAW insert input matches the same level as the DAW insert output (and all of your outboard gear you just matched). With everything now at unity, this should resolve the clipping.
Please let me know if this works.
